The purpose of this study is to determine whether T1
mapping sequence with fast multi-slice B1 correction
shows better diagnostic performance than T1 mapping
without B1 correction, for estimating liver function on
Gd-EOB-DTPA enhanced MRI. Postcontrast T1 relaxation
times (R1) with B1 correction of the liver on
Gd-EOB-DTPA MRI were significantly different among
different C-P score groups: 427.8145.8 msec in A5;
502.5134.9 msec in A6; and 640.9370.8 msec in B7
(P<0.001). As for R1s of the liver without B1
correction, values were 375.9156.8 msec in A5;
338.382.8 msec in A6; and 565.2336.2 msec in B7. T1
mapping using VFA and B1 correction can be used for
quantitatively estimate liver function using hepatocyte-specific
contrast enhanced MRI.
